With Ramadan looming, Yasiin Bey—formerly known as Mos Def—is protesting the force-feeding of Guantanamo prisoners by undergoing the procedure himself. To raise awareness for the more than 40 hunger-strikers who are force-fed at the prison each day, Bey underwent it himself for the video below, filmed for the human rights organization Reprieve. As you might expect, it’s absolutely horrible to watch, and even worse to imagine happening to someone—prisoner or not—day after day. And as the video itself warns, “Some viewers may find these images distressing.”
